Urban trees are often exposed to significantly greater loads and stresses than they would in their natural habitat. In the natural environment, trees often grow in protected microclimates with plenty of sunlight, rainwater and uncompressed soil filled with nutrients.
with higher temperatures in summer, impermeable surfaces such as asphalt and concrete, wind exposure, road salting in winter, heavy vehicle traffic, cyclists and pedestrians, as well as vandalism. A proliferation of paved areas allows no space for trees to grow and also prevents water and oxygen from reaching the roots.
that are actually available are also nutrient deficient and compressed. To a great extent, what is needed is prevention and planning to achieve lush and well-established trees. If space is limited, root-friendly soil cells can help to provide extra space for trees to develop roots. In addition, trees can be protected against future damage with tree pit grilles or tree guards.
